For those discerning GM vehicle owners that want only the best for their ride, the judicious attitude shouldn’t stop with fluids, filters, and maintenance. The fuel you put into the gas tank can be just as important, as some fuel is objectively better than others. As such, General Motors recommends only using Top Tier fuel, and now, GM Authority is making it easy to find Top Tier fuel retailers (or gas stations) to frequent for those fill-ups.
For those who may be unaware, Top Tier fuel is a fuel performance standard written by the world’s major automakers, including General Motors, Toyota, Volkswagen, Honda, FCA, and others. The standard is intended to maximize engine performance, improve fuel economy, and lower emissions by stipulating a higher level of fuel quality via stricter deposit control.
The automakers listed above felt as though the minimum deposit control requirements put forth by the EPA fell short of ensuring optimal engine performance. As such, in 2004, the Top Tier fuel economy standard was written for greater deposit control performance, thereby providing GM vehicle owners with assurance that the fuel they buy is of a high quality.
The Top Tier fuel designation is only given to fuels with a higher level of engine cleaning performance through the use of deposit control additives. Top Tier fuels cannot contain harmful metallic additives, and must be available across all octane levels of the associated fuel marketer’s stations.
These days, with the highly advanced engines equipped in modern GM vehicles, having the best possible fuel on board provides peace of mind that the engine will run at optimal levels of performance, returning maximum miles per gallon, lowering the environmental impact coming out the tailpipe, and of course, maximizing power when hitting the throttle. However, not all gas stations provide Top Tier fuel.
As such, GM Authority has provided a table that lists the retailers offering Top Tier fuel. Check it out below:
